摘要:

高级人类指令通常对应于具有多个隐式步骤的行为。为了使机器人在现实世界中发挥作用,它们必须能够对人类指令所暗示的运动和中间目标进行推理。在这项工作中,我们提出了一个框架,用于学习表示,从自然语言命令转换到一系列的中间目标,在机器人上执行。这个框架的一个关键特征是前瞻性,训练代理不仅要正确执行规定的命令,但采取it.We之前预测的一个动作的后果的地平线上展示了我们的框架所产生的计划的保真度时,解释真实的,众包自然语言命令的机器人在模拟场景。

英文摘要:

High-level human instructions often correspond to behaviors with multiple implicit steps. In order for robots to be useful in the real world, they must be able to to reason over both motions and intermediate goals implied by human instructions. In this work, we propose a framework for learning representations that convert from a natural-language command to a sequence of intermediate goals for execution on a robot. A key feature of this framework is prospection, training an agent not just to correctly execute the prescribed command, but to predict a horizon of consequences of an action before taking it. We demonstrate the fidelity of plans generated by our framework when interpreting real, crowd-sourced natural language commands for a robot in simulated scenes.
